The burden of atrial fibrillation and heart failure in hospitalized patients: A real-world survey in a nationwide snapshot.

Purpose: Atrial fibrillation (AF) and heart failure (HF) are common and commonly coexisting cardiovascular diseases in hospitalized patients. We report the absolute number and interrelation between AF and HF, assess the daily burden of both diseases on the healthcare system, and describe the medical treatment in a real-world, nationwide conducted snapshot survey.

Methods: A questionnaire was equally distributed to various healthcare institutions.

Myocardial perfusion SPECT as a potential mediator on circulating chromogranin A in patients with old myocardial infarction.

Objective: Chromogranin A (CgA) is a soluble polypeptide stored within and released from secretory granules of endocrine and other cell types (including cardiomyocytes); CgA appears to be a marker of the overall neuroendocrine activity. Increased levels of serum CgA have been found not only in patients with neuroendocrine neoplasms but also with other malignancies, hypertension, myocardial infarction, heart, or renal failure.

Subjects And Methods: A population of 307 patients (202 males, 105 females) was enrolled.

Arrhythmic risk stratification in post-myocardial infarction patients with preserved ejection fraction: the PRESERVE EF study.

Aims: Sudden cardiac death (SCD) annual incidence is 0.6-1% in post-myocardial infarction (MI) patients with left ventricular ejection fraction (LVEF)≥40%. No recommendations for implantable cardioverter-defibrillator (ICD) use exist in this population.

Patients with Atrial Fibrillation and Chronic Kidney Disease More Often Undergo Angioplasty of Left Main Coronary Artery - a 867 Patient Study.

Background/aims: Several studies have implicated atrial fibrillation (AF) as a contributing factor in chronic kidney disease (CKD) and cardiovascular events. The prevalence of coronary artery disease (CAD) in patients with AF varies substantially from 17% to 46.5%.
